Two types of CO2 radicals threaten the fundamentals of ESR dating of tooth enamel

Grun, Rainer; Joannes-Boyau, Renaud; Stringer, Chris

Description

In ESR dating of tooth enamel, dose values are usually obtained from powdered samples. It has been shown that the qualitative response of enamel powder to environmental and laboratory dosing is closely similar, thus apparently validating ESR protocols for dose estimation. When working on human fossils, their cultural and scientific value prevents the powdering of any samples. Measurements are carried out on enamel fragments instead. In fragments, natural and laboratory irradiations cause...[Show more]
